Description

Class Summary
BridgePatternConverter: The class implements the pre log4j 1.3 org.apache.log4j.helpers.PatternConverter contract by delegating to the log4j 1.3 pattern implementation.
BridgePatternParser: The class implements the pre log4j 1.3 org.apache.log4j.helpers.PatternConverter contract by delegating to the log4j 1.3 pattern implementation.
CachedDateFormat: CachedDateFormat optimizes the performance of a wrapped DateFormat.
ClassNamePatternConverter: Formats the class name of the site of the logging request.
DatePatternConverter: Convert and format the event's date in a StringBuffer.
FileDatePatternConverter: Formats an date by delegating to DatePatternConverter.
FileLocationPatternConverter: Return the event's line location information in a StringBuffer.
FormattingInfo: Modifies the output of a pattern converter for a specified minimum and maximum width and alignment.
FullLocationPatternConverter: Format the event's line location information.
IntegerPatternConverter: Formats an integer.
LevelPatternConverter: Return the event's level in a StringBuffer.
LineLocationPatternConverter: Return the event's line location information in a StringBuffer.
LineSeparatorPatternConverter: Formats a line separator.
LiteralPatternConverter: Formats a string literal.
LogEvent: This class is a copy of o.a.l.spi.LoggingEvent from log4j 1.2.15 which has been renamed to keep the same overall class name length to allow a serialization written with a prior instance of o.a.l.spi.LoggingEvent to be deserialized with this class just by mangling the class name in the byte stream.
LoggerPatternConverter: Formats a logger name.
LoggingEventPatternConverter: LoggingEventPatternConverter is a base class for pattern converters that can format information from instances of LoggingEvent.
MessagePatternConverter: Return the event's rendered message in a StringBuffer.
MethodLocationPatternConverter: Return the event's line location information in a StringBuffer.
NameAbbreviator: NameAbbreviator generates abbreviated logger and class names.
NamePatternConverter: Base class for other pattern converters which can return only parts of their name.
NDCPatternConverter: Return the event's NDC in a StringBuffer.
PatternConverter: PatternConverter is an abstract class that provides the formatting functionality that derived classes need.
PatternParser: Most of the work of the `EnhancedPatternLayout` class is delegated to the PatternParser class.
PropertiesPatternConverter: Able to handle the contents of the LoggingEvent's Property bundle and either output the entire contents of the properties in a similar format to the java.util.Hashtable.toString(), or to output the value of a specific key within the property bundle when this pattern converter has the option set.
RelativeTimePatternConverter: Return the relative time in milliseconds since loading of the LoggingEvent class.
SequenceNumberPatternConverter: Formats the event sequence number.
ThreadPatternConverter: Formats the event thread name.
ThrowableInformationPatternConverter: Outputs the ThrowableInformation portion of the LoggingEvent.
